"Bob is the oil Guy" is a website that professes to be independent of any oil company. They started out by publishing lab analysis of the various additive packages used in commercial name branded, and store branded oils. They sell nothing. They were started up much like SS, by a group of guys that wanted to know more about the oils they were blindly pouring into their much loved cars.I'm always amazed at some of the odd things that turn up on the internet.
Number one: just exactly who is "Bob the oil Guy" that works for an oil company, apparently his only qualification? Maybe he worked the register down at the local gas station.
Welcome
That should have been mentioned but wasn't. Judging by the clutter on the bench where the machine lives, I would say room temperature. The test apparatus was obviously derived from the Lucas Oil prop that is carefully positioned on the counters of automotive parts stores across the US. Lucas seems to think it is a valid test, so... fair is fair, I guess...Number two: under what conditions were the tests run? The only data had to do with a PS Ford, nothing to do with his demostration. I can take a bottle of vegatable oil out of the refrigerator, put it into the blender and whip up a batch of Cool Whip. What would that prove about a diesel engine? What RPM was used and it's relation to the real world? A few still photographs don't provide much in the way of scientific results.
How valid are all of the testimonials of seat of the pants truck drivers? We get lots of it's quieter, it feels better, it saved numerous transmissions for me, and the like, but no A-B tests, nothing but anecdote. In the course of my browsing around, I have found about a balanced number of accounts of good and bad results from the use of Lucas additives.
The lab tests the federal government had done on the old STP product showed bearings damaged by the extreme viscosity of the additive... The very thing being touted on this thread as being important.. STP was supposed to protect the bearings, but because it was so thick, it could not fit in the tight gaps in the bearings and starved them of needed lubrication. And yet guys like us swore by the stuff!
It costs money to ruin premium oils with different additives. The website is sponsored less well than Steel Soldiers.Number three: the rather limited oil samples? The results were against Schaeffers synthetic oil. Maybe in fairness if he had put Lucas in the Schaeffer's representitive and got the same results, it might mean something.
Lucas touts the additive as being suited for both gears and engines. The first set of tests were with gear oils that worked quite well without the additive, and got buggered with the additive. The second tests were with 15W40 engine oils.Number four: what exactly do open gears spinning in a sump of oil have to do with the conditions inside an engine with pressurized lubrication? The gears just represent the afore mentioned blender whipping air into the liquid. The oil plump pickup is under the surface of the oil in the sump no air to pickup. The oil drains down the sides of the inside of the engine giving it time to lose the entrained air it may have picked up. I'd be more impressed with a sight glass in the oil line of an operating engine.
Engines squirt high pressure oil out of the bearings, the wrist pins, and have open gears on the camshaft, distributors, IP's, and in the IP's. The crankshaft splashes in and out of the oil sump, rocker arms fling oil off of their ends... The MF engine specifically sprays oil on the undersides of the pistons to cool the combustion chambers. Even in relatively mild operation, engines whip up the oil quite nicely. To keep the foam to a minimum, the oil contains foam reduction additives. Look at the before and after pictures, the virgin oil's anti foam additive package is working pretty well in the test jig... until the Lucas is added.
Transmissions? Well they have gear stacks much like the test jig. Some of the gears turn really really fast too! We were talking about both applications in this thread.
I said it took two weeks, and the engine had 150,000 miles on it. Be generous, and stop assuming that I was doing stupid stuff with the PU truck. I drove it the same way before the failure, and I have driven it another 100K after the repair... all with my same conservative fuddy duddy way of driving.Number five: to condem all additives because you spun the bearings in one engine is fool hardy in my opinion. What was the history of the engine? How many miles when the Slick 50 was added? What was the RPM and engine temperature at the time the bearings spun? And most of all who bought the theory of powdered Teflon suspended in oil accomplished anything? I've seen more bearings spun by overreving a cold engine than anything else.
I bought the Slick50 story after hearing a slew of testimonials, much like this Lucas thread. I feared that the teflon would plug the oil filter, but was assured that it was milled finer than the oil filter could stop... I cut open the filter as part of my repair, and it showed no signs of the teflon, but had plenty of carbonized oil foam (which looked really wicked under my microscope). I was in the market for an additive package, because I really liked my truck, and I wanted something to extend the life of its front main bearing. Like most modern truck engines, mine had a severe, unbalanced, belt load due to the accessories, and pollution pumps. I knew from discussions with friends that ran machine shops, that the front bearings on my particular engine model were undersized, and prone to severe wear due to the oil film being squished out of the bearing (by the belt load) during the off times, and scuffing due to the lack of oil pressure at start up... Much like what most MF guys worry about.
I would believe that if Schaeffer was the only oil that was highly regarded by the site, but it isn't. The oils they put the Lucas into are also highly regarded by the site.My conclusion: somebody, maybe a clever salesman for Schaeffer came up with a way to condem a competitors product to sell more of his.
Use and little common sense and consider the source of anything you see on the web.
Take some time and browse through the site. There is more there than the bar stool talk that we are engaging in here on SS. They actually do testing on the oils, instead of just talking about them.
